VALVE FOR INTERNAL-COMBS'ION ENGINES.

Application led November 25, 1911.

To all whom t may concern.'

Be it known that l. RoneRT H. Aunis, ar citizen of the United Stat-es. residing' at Detroit. county of 'Yayne. State ot' Michigan, have invented a certain nenv and useful Improvement in Valves for internal- Conibustion Engines. and declare the followingT to be a full, clear, and exact description of the saine. such as Will enable others skilled in the art to which it pertains to make and use the same. reference beinghad to the accompanying drawings. which form a part of this specification.

ri`his invention relates to valves for internal combustion engines and has for its object a valve comprising slotted sleeves'one of Which is ldivided into compartments. These sleeves reciprocate across the head ot' the cylinders and control both the inlet and the exhaust ports.

In the draWingsz-Figure l, is a vertical sect-ion of the engine. of the'valve operating` mechanism.

is a casting forming the cylinders B. B and forming the Water jacket spaces C, C and lubricating conduits D. D, at the top of this casting'. Traversing the cylinder heads B is a bore F in-\vliich are fit-ted` the sliding sleeves H and G. .The i'orm of engine shown in the casting A is of the t\vo cylinder type andtour cycle variety. In the cylinder B are-located ports E and N. being the exhaust and the inlet ports. respectively. and these ports connect with the bore Likewise, in cylinder B1. near the top, are located the ports l and El, being the inlet and the `exhaust ports respectively, and connecting With the bore F ot the casting.

T he sleeves, of which H is the outer sleeve and Gr the inner sleeve, are the valves which control the exhaust and the inlet ports of the cylinders. The inner sleeve G is divided off into compartments by the partit-ions l, the middle compartment is the inlet compartment, While the end compartments are the exhaust compartments. lf more than two cylinders are employed an exhaust compartment may do duty for two cylinders in the samevvay as the middle inlet compartment operates. The exhaust compartment adjacent the cylinder B is put in communication with that cylinder, when the port e2 or" the sleeve H and the port' e3 of the sleeve G, each register with the port E into the cylinder. The compartment adjacent Specification of Letters Patent. PtQnLifel Fig. Q, is a top view` is, gioie.

Serial No. 662,289.

the cylinder B1 is put into communication vvith that cylinder. when the port c* of the sleeve H land the port c3 of the sleeve G, each register with the port E1 into the cylinder. The middle compartment or the inlet' compartment. may be put into communication with either cylinder. Communication with cylinder B being etlected by the registry of the pcrt n2 ot' the sleeve H and fn of the sleeve G with the port N into the cylinder. Connnunication with the cylinder El is eitected by the registry ot the ports n4 Vot sleeve H and 717 of sleeve (l With the port N1 into the cvlinder.

The perforated brackets 2 and 3 are fast to the ends of the sleeves H and G, respectively.l The connecting" rod 'el connect-s the bracket 2 with the crank (l on the counterhaft 5. While the connectingT rod 6 connects lhe bracket 3 with the crank c on the counter-shaft Tl ese cranks are arranged G5 degrees from center to center. The countershat't 5 carries a bev-el gear that meshes with' a bevel gear 8 on the shaft 9 that is 0peratively at halt the crank shaft, speed.

in Fig. l. t'he sleeves, or valves. are shown as they are when the cylinder B ias just exhausted and is about. to enter upon the intake stro-ke. while the piston off the cylinder B1 is on its Working stroke. rlhe bevel lgear 7 on the shaft 5 is revolving clockwise, so that the sleeve H is at the limit of its travel away from the countershat't 5, While the sleeve' G has yet. to travel to its limit away from the countershatt Ahe dotted lines show the position ot' the valves when the c vlinder B is takin@ in @as `While the piston of the cylinder B1 is on the Working stroke. it will be noticed that the port n2 and n3 register with the port N, so as to put the middle compartment of the valve into communication with the cylinder B. The inner sleeve G is also provided with ports in, and the outer sleeve H With-ports m1. The ports m and m1 of a particular compartment are in the form of elongated slots, so that a complete and unobstructed Apassage-ivav is afforded at all times from the manifold port m2 into the cylinder.

in the dotted lines of Fig. l, the position ot the valves' 's'vith respect to each other when the ports n and 'n3 register with the ort N, is shown. lt will be noticed that all the rest of the ports arevsov out ot registry and that each of the 'ports into the cylinder, except hl, are cut oil" from the oomthe proper time, is merelyY a matter ot me partnients, for at that moment the cylinder l taking' in gas, 'While the piston of the evlinder B1 is on its Working stroke. The placing ot the ports and the arranging of the reeiproeation of the sleeves so as to bring the ports in the sleeves in registry at elianieal calculation, which l will rnot describe, 'these would only be confusing, for it variable with thti position ot' the port into the Cylinder and the size of the port opening. Uil supplied to the valve through the eonduits l).

The form that l .hare shown in the drawii'ifgs has the bore and the sleeves disposed aeross the enter ot' the eylinder heads.- l'louever, the llore and the sleeves can be, located on the side of the cylinder heads and still come u'ithin theI spirit oi ni'v invention. A
